What peripheral blood counts warrant transplant consideration in FA?

Platelet <30,000/μL, neutrophil <500/μL, hemoglobin <8 g/dL requiring transfusion, or evidence of clonal evolution (MDS/AML) are standard transplant indications.

What is the chromosomal fragility test in FA?

Increased chromosome breakage in response to DNA crosslinking agents (DEB or MMC) is the gold standard FA diagnostic test; >10% breaks per cell strongly suggests FA.

What cancer risks are highest in Fanconi anemia?

AML/MDS risk (20-30% by age 40), squamous cell carcinoma of head/neck (particularly tongue) and anogenital region, and esophageal cancer are highest; post-transplant cancer risk remains elevated.

What androgen therapy is used in FA?

Oxymetholone (2-5 mg/kg/day) or danazol provides temporary hematological response in ~50% of patients; bridging therapy to transplant; does not prevent clonal evolution.

What reduced-intensity conditioning is used for FA transplant?

Standard myeloablative conditioning is too toxic in FA (DNA repair defect); fludarabine-based reduced-intensity regimens achieve successful engraftment with lower toxicity.

Fanconi Anemia Hematological Severity and Transplant Eligibility

Assesses Fanconi anemia bone marrow failure severity using blood counts, cytogenetics for clonal evolution, and FANCA/FANCB/FANCC complementation group for transplant eligibility and cancer surveillance scheduling.
